It holds the signals that direct cells to divide, differentiate and build themselves into a specific form.

This is the crucial step before cells differentiate and take on their various specialized roles.

In a complex organism like the body, cells are continuously differentiating.

Within the root hair zone is the region of maturation, where the cells differentiate.

Once the cells differentiate, they can be grown into whole plants and sampled for desired properties.

The cells differentiate just like the first time the finger grew.

Therefore, the cells differentiate from what they were meant to be.

Over the next several weeks, the cells differentiate into the type needed - in this case, cartilage.

The less healthy cells differentiate into the stalks of the fruiting body.

It's also an excellent model for how cells throughout the body differentiate.
